Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official Suntsu Electronics datasheet to ensure exact mechanical and electrical alignment. Confirm that the ±50ppm stability meets system requirements. Check for any recent lifecycle updates or alternative pin-compatible replacements if supply chain continuity is a concern. Ensure storage conditions comply with manufacturer guidelines for moisture sensitivity levels prior to soldering.

Crystals Selection Notes

Select this component when a 27 MHz frequency is required with moderate stability needs. The 11pF load capacitance must match the oscillator circuit design parameters. Consider the 100 Ohm ESR limit for driver strength compatibility. The wide temperature range makes it suitable for environments subject to thermal variation. Evaluate space constraints against the 4-SMD footprint dimensions before finalizing the PCB layout.

Crystals Part Context

This crystal belongs to the SXT series of surface-mount components from Suntsu Electronics. It serves as a fundamental passive timing element in active electronic systems. Unlike oscillators, it requires an external circuit to generate a square wave output. Its role is critical in synchronizing data transmission and processing speeds within digital logic families and embedded systems.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other 27 MHz crystals based on identical load capacitance, ESR, and package dimensions. Consult manufacturer substitution guides for potential equivalents if direct replacement is necessary.
